Check Digit Verification of cas no
The CAS Registry Mumber 112804-58-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,8,0 and 4 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 112804-58:
(8*1)+(7*1)+(6*2)+(5*8)+(4*0)+(3*4)+(2*5)+(1*8)=97
97 % 10 = 7
So 112804-58-7 is a valid CAS Registry Number.

General and practical carboxyl-group-directed remote C-H oxygenation reactions of arenes
Wang, Yang,Gulevich, Anton V.,Gevorgyan, Vladimir
, p. 15836 - 15840 (2014/04/03)
Two methods for remote aromatic C-H oxygenation reactions, have been developed. Method1, the Cu-catalyzed oxygenation reaction, is highly efficient for cyclization of electron-neutral and electron-rich biaryl carboxylic acids into 3,4-benzocoumarins. Method2, the K2S2O 8-mediated oxygenation reaction, is more general and practical for cyclization of substrates with electron-donating and -withdrawing groups (see scheme). Copyright
